R129 door position: flush, recessed or proud?

[Paul SL320]

Hi,

By adjusting the position of the lock striker located on the door aperture near to the rear wing I can set how far the trailing edge of the door sits inside or outside of the the rear wing.

But what is the correct position?

Should the trailing edge of the door be recessed just inside of the rear wing, be flush with the rear wing or sit just outside of the rear wing?

And by how much?

Thanks for your help

Paul

The door should line up with the wing (flush).
